Treatment of the gold 3-methoxy-3-phenylpropyl complex (P)AuCH2CH2CH(OMe)Ph [P = P(t-Bu)2o-biphenyl] with AlCl3 at −78 °C led to the immediate (≤5 min) formation of a 4:1 mixture of phenylcyclopropane and (1-methoxypropyl)benzene in 86 ± 5% combined yield. Lewis acid activation of the stereochemically pure isotopomer erythro-(P)AuCH2CHDCH(OMe)Ph led to the formation of cis-2-deuterio-1-phenylcyclopropane

The reaction of 1,3-dithiolane derivatives of ketones having α-hydrogen with lithium diisopropylamide results in fragmentation to the corresponding thioketone followed by further conversion in a few steps to the other intermediate species which, on trapping with alkyl halide, leads to a vinylic sulfide and/or a sulfide bearing a secondary alkyl group.

producing a rather stablecarboniumion, the thioether gives the chloride and an olefin, which are derived from the cation, the latter reacting also with the sulfenyl chloride to give adducts. There is another path to afford alkyl chloride; that is, an SN2-type reaction takes place when the alkyl part gives a less stablecarboniumion. The third and fourth products are α-chloro sulfide and α,β-unsaturated
